SPECIFICATION forming part of Letters Patent No. 397,881, dated February 12, 1889.

Application filed July 9, 1888. Serial No. 279,383. (No model.) Patented in England A ril 2'7,1886,N0.

To all whom it may concern Be it known that we, EDMUND TWEEDALE, SAMUEL TWEEDALE, and CHARLES MILLS, subjects of Her Majesty, the Queen of Great Britain, residing at Accrington, in the county of Lancaster, England, have invented a new and useful Improvement in the Driving Apparatus for Carding-Engines, (for which we have obtained a patent in Great Britain, No. 5,671, bearing date April 27,1886,) of which the following is a specification.

The object of our invention is to give a slow motion to the main carding-cylinder and doffer of cardingngines dnrin g the process of grinding the cards. For this purpose we connec1 the ordinary main driving-pulley and the pulley that drives the licker-in by casting the two in one part and by so arranging the same that when it is desired to decrease the speed of the cylinder and dot'fer for grinding purposes the driving takes place from a boss on said combined pulleys, the strap passing to a pulley for operating the doffer through slowmotion gearing, a pulley on the other end of the do ffer-shat't driving the cylinder at a slow speed by a strap passing toa pulley on the opposite end of its shaft. The pulley that drives the licker-in is employed for a strap which drives the grinding-cylinders, as will be hereinafter described.

To clearly explain the nature of our invention, reference is made lo the accompanying drawings, in which Figure 1 is an end elevation of sufficient of a carding-engine to illustrate our invention. Fig. 2 is a plan of the same, parts being in sec tion. Fig; 3 showsin section, on an enlarged scale, the combined pulleys, a small portion, however, being in elevation. Fig. i is an end elevation of the same, looking at it from the right-hand side.

The numeral 1 represents the driving-shaft of the cylinder 2, carrying a loose pulley, 32 and the pulley 3, which is cast in one piece with the pulley 5, a boss supplemental pulley or neck, 4, serving to connect the same. The pulley 5 drives the liclier-in 5 during the ordinary working of the machine.

011 the shaft 1 is secured, by a set-screw, 7, a boss or collar, 6, having the slotted wingpieces 6 6. This boss 6 is brought up close to the web 8 of the pulley 5, upon which are the projections 8 8, which have therein slots corresponding with those on the wing-pieces 6. When the shaft 1 is to drive the cylinder 2 in the usual way at its ordinary workingspeed, the bolts 9 9 are in the position shown in full lines in Figs. 3 and 4, thereby securing the combined pulleys to the fixed boss 6.

In order to obtain the requisite decrease of speed, the bolts 9 9 are shifted from the position shown in solid lines to the position shown in dotted lines into the slots of the projections 8, (where they are convenient of access when required again,) leaving the combined pulleys 3 and 5 loose upon the shaft 1. A strap, 11, Figs. 1 and 2, is then passed over the boss 4, which is thus utilized as a drivingpulley for operating the pulley 12,which drives the doffer 10 through the gear-wheels 13 14, as shown. The slow motion of the doffer so obtained is utilized i'or imparting a slow motion to the'main cylinder 2 through the pulley 15 at the opposite end of the doffer-shaft 15, the strap 16 of which drives the pulley 17 on the shaft of the cylinder 2.

- The grinding-roller 18, for grinding the cards on the cylinder 2, is driven by a strap, 19, which passes from the pulley 5 to the pulley of said roller, while the grinding-roller 18, for grinding the cards on the doffer 10, is driven by a strap, 19, from a pulley, 20, on the same shaft and somewhat to the rear of the pulley 20, said strap passing to the driving pulley 21 of the grinding-roller 18. In this way both the cards on the cylinder and the cards on the doffer are ground simultaneously. It will be evident though that the grindingrollers 18 or 18 may be operated separately for grinding the teeth on the cylinder alone or the teeth on the doffer alone.

It willbe understood that during the grinding of the cards the licker-in 5 is not in operation; hence the pulley 5 is available for use as described.

What we claim, Letters Patent, is-

1. In combination, driving-shaft 1, a pulley, nection between said pulley and desire to secure by the cylinder 2, the main 3, a detachable conand the main ioo shaft 1, pulley, l, a pulley, 17,

shaft 1, and the intermediate driving-conned tions between the pulleys 4 and 17, whereby the main shaft and cylinder may be driven indirectly and at a slow rate of speed through the pulleys 4- and 17 and intermediate connections, substantially as described.

2. In combination, the main shaft, the pulleys 2'3 and 5, with the connecting boss or pulley between them, a fixed collar or boss, ti, on

the main shaft having'slots, and the nuivable bolts 9, the pulley 5 being slotted to receive the bolts, substantially as described.

53. In combination, the main shaft, the cylinde1'2, the pulley 3, a detachable connection between said pulley and the main shaft, a supplemental pulley, 4, the doffer-shaft 15, and driving-connections between the dolfenshaft and the pulley i and between the doffer-shaft and as described. shaft, the 0y],
